What Does U0160 Mean?
Communication has been lost between the network modules and the audible alert control module (chime module). This prevents warning chimes and audible alerts from functioning, including seatbelt reminders, door ajar warnings, and other safety notifications.
Common Causes

Diagnostic Steps
1
Step 1: Verify power and ground supply to audible alert module using multimeter
2
Step 2: Inspect module connector for corrosion, bent pins, or water damage
3
Step 3: Check CAN bus communication signals at module connector (CAN High/Low voltages)
4
Step 4: Test module operation by triggering known chime events (door open, key in ignition)
5
Step 5: Swap module with known good unit if available to confirm module failure
Estimated Repair Cost
